题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.
 
The argument above requires which of following assumptions?

选项:

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.

One summer, floods covered low-lying garlic fields situated in a region with a large mosquito population. Since mosquitoes lay their eggs in standing water, flooded fields would normally attract mosquitoes, yet no mosquitoes were found in the fields. Diallyl sulfide, a major component of garlic, is known to repel several species of insects, including mosquitoes, so it is likely that diallyl sulfide from the garlic repelled the mosquitoes.

Which of the following, if true, most strengthens the argument?
请问胡凡老师，， 这道题逻辑链是通过一个现象no mosquitoes were found in the field且garlic会驱赶包括蚊子在内的昆虫 得出garlic repelled了蚊子吗？ 这道题d选项是无因无果吗？ 无因无果的本质是否可以理解为若没有这个因，则不会产生这个果，排除了其他原因会影响结论吗？

一直没有明白C的错误到底在哪里，看了两个回答，都说that如果表示total fat的话，只能表示wild animal的,为什么不能是livestock的呢？比如，I have less apples than that of Eric,这个that 不能表示Eric的apples吗？

After decreasing steadily in the mid-1990's, the percentage of students in the United States finishing high school or having earned equivalency diplomas increased in the last three years of the decade, up to 86.5 percent in 2000 from 85.9 percent in 1999 and 84.8 percent in 1998.
看到who跟在united states后面觉得并不能很好地直接修饰到students，会有歧义，因为主语是个名词所有格，就排除了. 平时如何判断怎样的修饰指代是清晰的呢？谢谢

Educational Theorist: Recent editorials have called for limits on the amount of homework assigned to children. They point out that free-time activities
play an important role in childhood development and that large amounts of homework reduce children's free time, hindering their development. But the
average homework time for a ten year old, for example, is little more than 30 minutes per night. Clearly, therefore, there is no need to impose the limits these editorials are calling for.
 
Which of the following is an assumption on which the educational theorist's argument relies?
选了E请问老师E哪里不好，我认为E说明了课余时间没有用于学习，所以排出了课余时间增加学业负担的可能
